EnvirOzone Technologies' proprietary process and
apparatus are both patented and have been recognized by the EPA as
an effective method of waste water treatment and remediation as well
as an effective potable water treatment process.
U. S. Patent #5,180,499-Process for removal of solid
chemical and bacterial waste from water, and #5,308,480-Apparatus
for removal of solid chemical and bacterial waste from water, were
registered to EnvirOzone in 1993 and 1994 respectively.
EnvirOzone's process meets or exceeds current and
upcoming regulatory guidelines for the Safe Drinking Water Act, the
Surface Water Treatment Rule, the Disinfectant/Disinfection By-Products
Rule and treatment of contaminated ground water.

Process Overview
EnvirOzone Technologies, Inc. offers an environmentally
safe process for the treatment and/or reduction of contaminants in
water. Since the levels and types of contamination vary with our clients'
requirements, these units are designed to demonstrate the process
and feasibility of treating specific applications. The design and
cost of a specific unit will vary depending on the quality and quantity
of the water to be treated.

The advanced oxidation and separation process is
designed to separate fats, oils, greases, and solids, and to oxidize
organic substances to carbon dioxide and water. It has been extremely
effective in the treatment of waste water generated in petroleum,
agricultural, food processing, municipal waste, and drinking water
applications. Contaminants such as cyanide, phenol, benzene, diesel,
toluene, xylene and a variety of pesticides, herbicides, and solvents
have been reduced to a few parts per billion or non-detectable levels.
The process has also dramatically reduced BOD and COD levels.
TECHNOLOGY
EOT's patented system is a two-module, multi-phase
treatment process designed to destroy bacteria and viruses and oxidize
numerous chemicals in aqueous streams.
The physical and chemical processes used in our system
are not new. It is the synergy present when these chemical and physical
processes are combined and controlled in the EOT system that is new.
ENGINEERING PRINCIPLES
Our patented system is comprised of two treatment modules:
Module One - Micro Dissolved Air Flotation (Micro-DAF)
This first treatment module consists of a two-stage, multi-phase system
that facilitates the removal of fats, oils, greases, and suspended
solids through fluidization and ozone micro-flocculation. In this
module, the oxidation of contaminants is initiated.
Liquid waste is first intimately intermixed with
a gaseous oxidant comprised of ozone and oxygen. Solids are removed
through flocculation and flotation. The waste is then re-saturated
with oxidant for the breakdown and destruction of chemical and bacterial
wastes.
Module Two - Micro-Ozonation This
second module provides a highly efficient oxidation environment for
the final treatment stages for the effluent from Module One. The influent
is saturated with ozone for a pre-determined period of time and circulated
through the system for re-treatment. The treated water undergoes exposure
to ultra-violet light and is finally degasified prior to discharge
from the system.
CHEMICAL PRINCIPLES
Chemical processes occur in concert with and are
aided by the physical processes in EOT's treatment system.
The actual number of key chemical reactions occurring
in our system is in the dozens, however, four generic reactions summarize
this chemical activity:
- ozonation
- oxidation
- hydroxylation
- de-ozonation

All of the technologies used in the EOT treatment
are enhanced by the outstanding oxidizing power of ozone (O3).
The powerful oxidizing properties of ozone are coupled
with our proprietary process of feeding it into the waste stream in
the form of billions of highly reactive bubbles. This gives ozone
the desired properties in oxidizing hydrocarbons as well as other
chemicals in the liquid waste stream.
It is the release of energy, however, which is liberated
in the spontaneous chemical reaction of ozone to ordinary oxygen,
which enhances and maximizes the oxidizing power of ozone.
Finally, the treated water can be directed through
beds of granulated activated carbon (GAC). Additional contaminants
are absorbed and any excess ozone is converted to oxygen. The treated
effluent is discharged from the system.
